Kassim Osgood mumbled a few obligatory answers in Jacksonville’s locker room after the blowout inflicted by his former team. But, really, there wasn’t much to say about a sour homecoming to Qualcomm Stadium.

Osgood, the special teams stud out of San Diego State who left the Chargers after seven seasons in the hope of becoming a regular receiver, was targeted for only two passes by his quarterbacks and didn’t make a catch. Last week, he had only one reception, but it was for the game-winner.

Even when Osgood apparently made a spectacular play on special teams, he really didn’t.

The PA announcer mistakenly credited Osgood with a block of Mike Scifres punt in the second quarter. Rashad Jennings, a reserve running back, actually made the play, knifing in from the left side to get a clear shot at Scifres, who only one other punt blocked in his career, in 2007.

Morrison on losing end again

San Diego State product Kirk Morrison switched jerseys this season, from the Raiders to Jags, but the linebacker still can’t get a win on his former home turf. He was 0-5 with Oakland playing in San Diego, and now 0-1 with J’ville.

“It’s frustrating,” Morrison said. “They’re an opportunistic team and they make big plays. Things kind of snowballed on us.”

TD Tolbert

Our sports editor, Jay Posner, says that if you didn’t use at least a late-round draft choice to pick Chargers fullback Mike Tolbert for your fantasy team, you didn’t do your homework. Tolbert, not Ryan Mathews, could be the go-to guy on goal-line situations this year, even when the rookie is healthy. The dude can move a pile with the best of them, and it saves wear and tear on Mathews, who is already nursing an injured ankle in Week 2.

Tolbert’s Sunday line: two goal-line attempts, two TDs.

Mathews scare

It looked very, very bad when Mathews went down in the second quarter after getting crunched in a pileup after a run. A cart hauled Mathews to the locker room, but he trotted out before the half was over, drawing a round of relieved cheers.

Wisely, he didn’t enter the game again.

Garrard’s awful day

Another visiting QB had the kind of game that makes Philip Rivers looks so special. Jags starter David Garrard threw four interceptions and had a QB rating of 62.7, compared to Rivers’ 119.0. In the last two seasons, Garrard has eight games with ratings above 100 and eight in which he was below 65.

Admitting concern about the inconsistency, Jags coach Jack Del Rio said, “The quarterback is the trigger. If he has a rough day, generally speaking, it’s going to lead to a rough day for your football team.”

Said Garrard: “I have to be better, period. I’m not going to shoulder all of the blame for the quarterback rating, but a lot of it’s on me.”

Jersey exchange

There are some Chargers fans who are going to have to bite the bullet and shell out cash for new jerseys. In the field-level seats on the home side, there were quite a few diehards who haven’t given up their LaDainian Tomlinson 21s and, and for those donning the 83 of Vincent Jackson – boy, are you dreaming. Rivers’ 17 appears to be the best seller, but gaining fast is Mathews’ 24.

Igor, really?

To the man and woman still sporting Igor Olshansky’s 99: He was a Cowboy LAST YEAR, and it’s not like he’s going to end up in anybody’s Hall of Fame.

Pyromania

The Chargers added some, uh, heat to their pregame introductions and touchdowns with a contraption that shoots two flames into the air, as well as some fireworks. Hear that the next game’s giveaway is chocolate and marshmallows for S’mores.

Punting drought

If you’re a punting connoisseur, 1) get a life; 2) you must have been extremely disappointed with the game. After last week’s punt fest at Kansas City (17 kicks), there were exactly two punt attempts Sunday, both by the Chargers, including the block. Incredible that the Jags lost by 25 points and didn’t punt, but that’s what happens when you have six turnovers.

Mr. Fix It

In the elevator heading to the press box before the game was Mr. “Home Improvement,” actor Tim Allen. No truth to the rumor he was here to fix the Chargers’ special teams.
